Messaging service Whatsapp suffered a crash this morning sending its users to panic as they cannot send or receive messages, photos, and videos, files for more than an hour that the site was down.

Whatsapp users took to other social media platforms to air their frustrations with the site outage in what became apparent as a global problem.

Users in much of Europe, Asia, and the U.S. were most affected. Many took to social media to report their problems with their Whatsapp accounts in their respective countries including those here in the U.S., London, China, India, Saudi Arabia, Indonesia, Malaysia, Sri Lanka, among others.

There were also speculations that went around suggesting that the crash was caused by a hack. Whatsapp, however, did not confirm such angle to explain the glitch.

Website DownDetector also published a map showing more than a thousand of the site’s users reporting issues and difficulties with Whatsapp. Close to 60 percent of Whatsapp users is estimated to have been affected by the crash.

The issues with the messaging service appeared to have been resolved already hours into the initial reports of the crash. Only a handful of users across the world are reporting on access problems with Whatsapp.

Whatsapp as a chat app is owned by social media giant Facebook. This is also not the first time that the popular messaging app suffered a glitch this year. It also went offline for thousands of its users sometime in May. The outage then lasted for some hours, and Whatsapp was then forced to issue the official statement about the disruption in their services.

Also only earlier this month, Whatsapp suffered another worldwide outage with hundreds of users reporting that they were affected.

WhatsApp was bought by Facebook in February 2014 for a whopping $19 billion. It counts 1.2 billion users worldwide.
